Description

Technical Field

[0001] This invention belongs to the fields of transportation and CO2 capture technology, and specifically relates to a smart network that integrates vehicle traffic and CO2 collection functions. Background Technology

[0002] Human activities have caused a significant increase in greenhouse gases in the atmosphere, leading to a series of severe climate problems. Reducing greenhouse gas emissions and mitigating the greenhouse effect is of paramount importance.

[0003] Mobile carbon sources, represented by motor vehicles and non-road mobile sources, are characterized by their dispersed distribution, small emissions per source, and large number. Once generated, CO2 is immediately emitted into the atmosphere. Therefore, emission reduction methods targeting mobile carbon sources require, to some extent, the participation of negative emission technologies (NETs). NETs refer to technologies that enhance natural carbon sinks or directly remove CO2 from the atmosphere. Direct carbon capture (DAC) technology, as a typical negative emission technology, has the advantages of flexible deployment and a wide range of unit sizes. Furthermore, as a safety net technology for carbon neutrality, DAC can achieve a real reduction in atmospheric CO2 concentration, making it indispensable for achieving the "dual carbon" target (carbon neutrality and carbon eradication).

[0004] Atmospheric CO2 concentrations vary significantly across different regions of the Earth. In forest and wetland areas, atmospheric CO2 concentrations are below average, around 350 ppm, while in urban and transportation-intensive areas, concentrations are above average, even exceeding 600 ppm in industrial and transportation-developed regions. Implementing carbon capture-depletion (DAC) technology in areas with high atmospheric CO2 concentrations can reduce energy consumption and costs. Simultaneously, to achieve long-term and stable removal of atmospheric CO2, the CO2 captured by DAC technology needs to be stored in conjunction with carbon sequestration (CFS) technology. Currently, the implementation of DAC (Carbon Depletion and Storage) projects faces spatial and economic mismatches with the CO2 capture and storage process. Firstly, atmospheric CO2 concentration is positively correlated with population density and regional economic development, contradicting the spatial scale and cost of DAC facilities. High CO2 concentration areas are suitable for DAC operations, but large-scale centralized DAC facilities are impractical due to their high space costs. Secondly, CO2 storage sites are typically located in sparsely populated areas, far from industrial zones and cities, such as depleted oil reservoirs and seabeds. These sites are concentrated and located at considerable distances from CO2 capture areas, necessitating CO2 transportation as a crucial link between carbon capture and storage. These issues mean that captured CO2 must be transported to storage sites by car, ship, or pipeline, a process that consumes significant amounts of additional energy and generates additional carbon emissions. Summary of the Invention

[0005] This invention proposes a smart network integrating vehicle traffic and CO2 collection functions, primarily based on a method for capturing CO2 from the air using a mobile DAC (Digital Converter) and an electric vehicle charging / swapping network. This method utilizes a mobile DAC integrated into an electric vehicle to capture CO2 from the air, and then uses the electric vehicle charging / swapping network to collect it. Finally, the collected CO2 at an economically manageable scale is transported to storage or utilization sites. This airborne CO2 capture method based on a mobile DAC and an electric vehicle charging / swapping network effectively reduces CO2 capture energy consumption, lowers CO2 capture, collection, and transportation costs, and effectively alleviates the contradiction between the dispersed distribution of CO2 in the atmosphere and the current concentrated distribution of CO2 treatment points.

[0006] To achieve the above objectives, the specific solution adopted by the present invention is as follows:

[0007] A method for capturing CO2 in the air based on a mobile DAC and an electric vehicle charging and swapping network includes three steps: CO2 capture, CO2 collection, and CO2 sink processing.

[0008] The three steps involve three main processes. First, a CO2 capture process is performed, integrating a mobile DAC (Capture Deposition Unit) device into the electric vehicle. During the vehicle's operation, CO2 is captured from the air using a capture medium or membrane. The mobile DAC device is powered by the vehicle's residual energy or external energy source. The captured high-concentration CO2 or CO2-saturated capture medium is then transferred to the ground for desorption, yielding high-concentration CO2. Vehicle driving data and DAC data are recorded during the CO2 capture process. Second, a CO2 collection process is performed. A CO2 collection network is designed using the data recorded during the capture process. Primary CO2 collection points are set up at electric vehicle charging / swapping stations. When the electric vehicle enters the station to replenish its power, the captured high-concentration CO2 is transferred to a large-capacity storage tank at the primary collection point, achieving CO2 collection. Finally, based on the operational data of the CO2 collection and sinking network, the network is optimized. The CO2 collected in the network is then transported to carbon sinks such as oil fields and brackish water layers for final processing.

[0009] The CO2 capture process mainly utilizes a mobile DAC device mounted on an electric vehicle to capture CO2 from the air; wherein:

[0010] The mobile DAC device has its air inlet located on the windward side of the vehicle. The air volume is adjusted by the area of ​​the air inlet, and the wind speed is adjusted by the air duct structure.

[0011] In the mobile DAC device, absorbents, adsorbents, etc., can be used as the capture medium, or a membrane can be used;

[0012] When the mobile DAC device uses an absorbent or adsorbent as the capture medium, different configuration schemes need to be adopted according to the amount of CO2 that can be captured by the electric vehicle in a single charging cycle and the amount of CO2 captured by the capture medium in the mobile DAC device in a single cycle.

[0013] In the aforementioned configuration scheme, when the amount of CO2 that the electric vehicle provides to the DAC device in a single charging cycle is much greater than the amount of CO2 captured by the capturing medium in the DAC device in a single cycle, the mobile DAC device should include a capturing medium regeneration device and a CO2 storage tank, so that high-concentration CO2 is desorbed and stored in the storage tank while the capturing medium is regenerated.

[0014] In the configuration scheme, when the amount of CO2 that the electric vehicle provides to the DAC device in a single charging cycle is less than or equal to the amount of CO2 captured in the capture medium in the DAC device in a single cycle, the mobile DAC device may only include an absorption / adsorption device, and the captured CO2 is temporarily stored in the capture medium.

[0015] In the mobile DAC device, when CO2 capture is accomplished using membrane separation, the captured high-concentration CO2 is stored in a storage tank.

[0016] The external energy source mentioned includes, but is not limited to, photovoltaic, solar thermal, and other energy sources that can be used to provide energy for fans, circulating pumps, desorption equipment, etc. in the DAC device;

[0017] The method of transferring the captured high-concentration CO2 or CO2-saturated capture medium to the vehicle includes pipelines and replacing the capture medium;

[0018] The mobile DAC device has the function of recording and uploading operating data. The data recorded during the specific driving process includes, but is not limited to, speed, location, CO2 concentration in the area, capture efficiency, charging and swapping frequency, and capture amount.

[0019] The CO2 collection process involves designing a CO2 collection network based on vehicle driving data and CO2 capture data recorded by the mobile DAC device, and optimizing the charging and swapping stations for electric vehicles, CO2 collection routes, and the capture capacity of the mobile DAC device through runtime data feedback analysis.

[0020] The CO2 sink processing process optimizes the CO2 sink processing network by adjusting the location of primary CO2 collection points, adding or reducing secondary CO2 collection points, and adjusting the scale of the CO2 collection pipeline network, based on the operating data of the CO2 collection / sink processing network.

[0021] Preferably, the primary collection point can be set up at a charging and battery swapping station with high CO2 capture efficiency;

[0022] Furthermore, when factors such as the scale and distance of CO2 transportation between the primary CO2 collection point and the CO2 sink cannot meet the requirements of economical transportation, a secondary collection point can be set up. The secondary collection point receives CO2 from multiple primary collection points, thereby increasing the scale of CO2 transportation and shortening the transportation distance, thus reducing the CO2 transportation cost between the collection point and the sink.

[0023] The beneficial effects of this invention are as follows:

[0024] This invention provides a smart network integrating vehicle traffic and CO2 collection functions. It is a method for capturing CO2 in the air based on mobile DAC devices and electric vehicle charging / swapping networks. The method uses DAC devices mounted on electric vehicles to capture CO2, and combines this with the charging / swapping network for CO2 collection. The collection / sinking processing network is further optimized based on DAC data and driving data. This method achieves low-energy, flexible, and convenient decentralized capture of CO2 in the air. Through hierarchical CO2 collection and processing, and by combining vehicle driving data and DAC capture data, the entire chain of the CO2 capture-collection-sinking processing network is optimized. This effectively alleviates the contradiction between the dispersed distribution of CO2 in the atmosphere and the concentrated distribution of current CO2 processing points, improving the economics of CO2 capture and storage.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1As shown, this invention proposes a smart network integrating vehicle traffic and CO2 collection functions, specifically a method for capturing CO2 in the air based on a mobile DAC (Digital Converter) and an electric vehicle charging / swapping network. During the operation of electric vehicles, a mobile DAC module is used to capture CO2 in the air in a dispersed, efficient, and low-energy-consumption manner. The electric vehicle charging / swapping process is integrated with the CO2 collection system to achieve the collection of high-concentration CO2. Finally, the CO2 collected to an economically viable scale is transported via pipelines or transport vehicles to CO2 sinks for storage / utilization for further processing.

[0030] Example 1: The amount of CO2 captured by the electric vehicle in a single charging cycle is much greater than the amount captured by the capturing medium in the DAC device in a single cycle. The electric vehicle charging and swapping network adopts a charging pile model, and the CO2 collection system adopts a direct CO2 collection method; as shown in the attached... Figure 2 As shown, electrical energy is transmitted from the main power grid and the renewable energy auxiliary power grid, from centralized to decentralized electric vehicle charging and swapping networks, to replenish the energy of electric vehicle terminals. CO2 in the air is captured by mobile DAC modules mounted on electric vehicles. The high-concentration CO2 obtained is initially collected by a CO2 collection system based on the electric vehicle charging and swapping network. The CO2 collected by the collection system is then transported via pipelines or transportation vehicles to CO2 sinks for storage / utilization and other processing at an economically viable scale.

[0031] Example 2: The amount of CO2 captured by the electric vehicle in a single charging cycle is much greater than the amount captured by the capturing medium in the DAC device in a single cycle. The electric vehicle charging and swapping network adopts a charging pile model, and the CO2 collection system adopts an indirect CO2 collection method; as shown in the attached... Figure 3 As shown, when the CO2 desorption process takes place under the vehicle, the CO2 is fixed in the CO2 capture medium by the onboard mobile DAC module. The CO2-loaded capture medium is removed through the CO2 extraction device of the CO2 collection system, and then regenerated in the CO2 regeneration device for CO2 desorption. Simultaneously, the regenerated CO2 capture medium is replaced for the vehicle's CO2 air capture system. The CO2 collected by the collection system is transported via pipelines or transport vehicles to CO2 sinks for storage / utilization after reaching an economically viable treatment scale.
